Just to share how I fit a round pre-cleaner that found on ebay store. The main clamp came soldered so i grinded of that clamp,you have to make the inside inlet of the safari snorkel a little bit bigger then re-use the black clamp that came with the old head. Online store asking price for the same type was $65.00 + shipping.
